Anti‑Clog Self‑Cleaning Screw Sludge Dewatering Machine Low‑Maintenance Dehydrator for Viscous Oily Fibrous Industrial Sludge Treatment

Anti‑Clog Self‑Cleaning Screw Sludge Dewatering Machine Low‑Maintenance Dehydrator for Viscous Oily Fibrous Industrial Sludge Treatment

Brief Description

Self‑cleaning WXDL screw sludge dewatering machine excels at viscous, oily and high‑fibre sludge. Unique moving‑ring self‑scraping mechanism avoids filter‑gap blockage that troubles traditional dewatering equipment. Reduce manual cleaning & downtime, cake moisture reduced to approx 80% for difficult‑to‑treat sludge.

Product Overview

This unit is specially optimized for sticky / oily / fibrous sludge conditions. Dewatering host adopts fixed‑&‑moving‑ring filter stack; moving rings reciprocally driven by screw spindle. Built‑in spray‑washing assembly works together with mechanical self‑cleaning to prevent fibre or oil residue accumulation. The whole set contains dewatering main body, flocculation mixing system, spray washing assembly and electric control. Suits sludge concentration 5000‑50000 mg/L with tough properties.

Product Parameters

Working Principle

After flocculation conditioning, viscous/oily sludge enters filter chamber. Gravity thickening removes free water at inlet section. Variable‑pitch screw spindle pushes sludge forward into high‑pressure extrusion zone, back‑pressure plate creates incremental squeezing pressure to discharge bound water. While spindle rotates, moving rings slide reciprocally relative to fixed rings, mechanically scraping filter gaps to strip sludge fibre and viscous residues. Auxiliary spray‑washing further washes filter stack; sludge cake is continuously discharged.

Key Design & Performance Features

1.Wide sludge concentration adaptability: 5000‑50000 mg/L inlet sludge.

2.Integrated unit design for easy installation.

3.24‑hour fully‑automatic continuous operation.

4.Self‑cleaning filter stack plus spray rinsing against blockage.

5.Fully‑enclosed structure to control odor emission.

6.Low‑speed spindle (2‑3 r/min), low vibration & noise.

7.Stainless‑steel key wetted components for corrosion resistance and long service intervals.

Applications

Municipal wastewater treatment plants, food & beverage processing, slaughterhouses, textile dyeing, papermaking, chemical manufacturing, pharmaceutical factories and general industrial wastewater facilities.
